Jonathan Hibner, 33, of York, pleaded guilty on Monday to aggravated assault. As part of a plea agreement, prosecutors dropped the remaining charges against him, which included terroristic threats, cruelty to animals and burglary.

"It was a negotiated plea, and I think the interests of justice are being served," said Roger Laguna Jr., Hibner's attorney, outside the courtroom. "I think it's a reasonable resolution."

On Feb. 10, 2017, Hibner — it was his birthday — broke into Michelle Leister’s apartment on York Haven Road with a knife and stated, “I’ll kill you if you call 911,” Newberry Township police said. They had been texting earlier. During the assault, police said, he stabbed her pit bull when it “apparently intervened.”
